The washing machine body 4 isprovided with a channel plate 24 preferably consistin of a castin and fitting an end transverse ar 25 of t e Washing machine body and provided with spaced depending ears 26 between which the upper end of the link rod'23 is pivoted. The lower end 27 of the link rod is enlarged and bifurcated and it straddles and is' pivoted to the outer terminal portion of the arm 16 of the walking beam or lever. The other arm 17 of the walking beam or lever is provided with a pivoted loop or shackle 28, which is connected to the lower end of a coiled spring 29.'and the latter yieldably connects the washing machine body with the arms 17 of the walking beam or lever. The upper end of the coiled spring is sc cured in an eye 30 of a channel plate.or piece 31, which is bolted or otherwise fastened to the adjacent transverse bar 32 of the .shing machine body. Thclink rod forms-.i positive connection between one end of. the washing machinebody and the coiled spring constitutes a yieldable connection between the walking beam and the other end of the washing machine body, and the connecting means is adapted to conform to theconstantly shifting of the fulcrum point of the rockers on the base of the'washing machine andpermits an easy operation of the washing machine without straining the parts. The spring also assists in holdin the rockers to the base and jumping thereon. I

.The arm 18, which extends upwardly from the central portion of the walking beam or lever, has a forked or bifurcated upper end 33, which is pivoted to the upper end ofa pitman' 34. extending downwardly and outwardly from the intermediate arm 18 to a wrist pin 35 of the crank disk 22, whereby when the crank disk is rotated. the walking beam or lever willbe oscillated for rocking the washing machinebody on the base. Any other preferred form of crank element may, of course. be employed. and the said crank disk is mounted on an inner or rear section 36 of a. transversely disposed transmission shaft composed of the said inner orrear section 36, and a front or outer section 36.

The front or outer section 36" carriesa spur gear Wheel 37 fixed to the front section 36" by a key, clamping screw, or other suitable bearin fastening means and meshing with aipin ion 38 of a driving shaft 39. The driving and transmission shaftsare ournaled in suitable bearings of' the frame 21, which is I composed of spaced sides and integral connecting end portions, one of the sides of the frame .being secured to the adjacent, side 0 the base and the bearing frame beprevents them r0m ing provided at the opposite side with a longitudinally disposed arm 40, which is seecured to one end of the base. The bearing frame 21 which is preferably flanged as shown, is located adjacent to one corner of the base, as clearly illustrated in Fig. 2 of the drawings, and it extends beneath the adjacent side and end bars of the base and is provided with upwardly projecting ears or flanges 41 arranged at the said side and end bars of the base and pierced by bolts or other suitable fastening means, which secure the bearing frame to the base. The

driving shaft 39 projects from one side of the base and has mounted on it a driving )ulley 42, which is designed to be connected y a belt with a suitable motor or engine. The gear wheel 37 which is continuously rotated when the driving shaft is actuated,

has an extended hub 4:2 receiving the ad jacent ends of the front and rear sections of the transmission shaft. the inner ends of the sections being illustrated in the drawings as slidablv supported in order to show the construction more clearly. but in practice the sections will substantially meet.

vided at the terminal portions of the slot- 'The extended hub 42*} is provided at the end with a clutch face 43-adapted to inter;

with notches 52. adapted to receive the clutch operating lever for holding the slidable clutch section into and out ofengagement with the clutch face of the gear Wheel 37. The clutch lever is extendedbeyond the catch or keeper and its outer terminal portion constitutes a grip or handle. When the slidable clutch section 45 is engaged with the clutch face of the gear wheel 37,

the. \'ieldi-ng beam is actuated and oscillates the washing machine body on the base. The front seet1on'36 of thejtransrnission shaft projects outwardly beyond the base and extends into a lower gear case.53, and carries a vertical bevel plnion 54 transmission shaft, so as to be continuousl y'ed or otherwise fixed to the front section of the rotated when the driving shaft is actuate The vertical bevel pinion 54 meshes with a horizontal bevel pinion 55 secured to the lowerend of a vertical shaft 56. The gears 54 and 55 are housed-within the lower gear case 53, which onstitutes cheering for the lower portion of the vertical shaft 56, and

' tical gear58, a'rrangedwbetween and adapted 1 to mesh witheitherone ofa pair otvertical bevel pinions or'agears 59, mounted on an extension 60 of the lower roll 61. of l the wringer. The vertical-"bevel plnions 59 are preferably formed integral with the sleeve 'me'sh with the gear 58.

62, slidably interlocked with the shaft or the lower wringer roll 1 and adapted to be shiftedalong the same to carry either of the gears 59 into mesh with the gear 58 and the vertical shaft and also to ar 'ange both of the gears 59 out of mesh with the gear 58. By this construction the lower wringer roll is adapted to be rotated in either direct-ion and also to be thrown out of operation when desired. The gear'sBS :lllll 39--are housed within the upper gear: case. which is provided with a removable section 63. i The sleeve (32 is provided with a central annular groove 64: preferably formed by spaced annular flanges and engaged by a, forked'portion 5 of a clutch operating lever 66, extending upwardly from the sleeve 62 and fulcrnmed at an intermediate point in the gear case by a pin 7 or other suitable pivot and connected at its upper end with an operating rod 68. The operating rod 68 extends acrossthe top of the wringer and is supported at the op posite side thereof from that at which the gearing is located by a link or lever 69, pivoted at its lower end 70 to a lug or pro-, jection of the wringer and pivotally, con neeted at its upper end to the adjacent end of the operating rod 68. The operating rod 8 is adapted to be shifted longitud1 nally to throw the gears 59 into and out of By means of the shifting mechanism at the wringer and the clutch operating mechanism at the'base ot the washing machine, either the Wringer or the washing machine may be thrown into and out of operation.

instead of constructing the transmission shaft in two sections, a continuous shaft extending entirely acrossthe bearing frame maybe employed, lhe crank element being secured to the inner or rear end of the same and the lower gear 37 and the pinion 54 being connected bva sleeve and rotating" bn the front portion of the transmission shaft. 'VVith this construction, the lower clutch will operate to connect the ,{tran mission shaft with the lower gearing lo throw the washing mechanism into and our of operation. l
